Summary

DirectShow Capture Graph settings class.

Description

Defines the class for DirectShow Capture Graph settings.

Events

• OnVideoGrabberCreate - Occurs before the video grabber filter is created.
• OnReleaseFilters - Occurs when the graph filters are being released(The graph is destroyed.).
• OnAfterRendering - Occurs after the Graph has been rendered(All the filters are created and connected.).
• OnCustomRender - Occurs during the DirectShow Graph rendering.
